2015 Hyundai Sonata: A Refined Entry In A Crowded Segment

A Familiar Infotainment System

Standard on the base Sonata SE is a six-speaker stereo with AM/FM, SiriusXM, CD, MP3, USB and auxiliary input. It’s iPod- and iPhone-compatible with voice commands. You even get 600MB of on-board storage for copying music files to. At the heart of the base radio is an ARM processor clocked at 333MHz, though more specific information about the exact SoC being used isn't available.

Stepping up to the Sport and higher trim levels adds a 5-inch LCD touchscreen, Blue Link telematics and a back-up camera. The SoC doesn't change, though. The 5-inch display is fairly low-resolution, but it does make navigating flash drives loaded with music easier to manage.

Check the tech package option and your infotainment system gets upgraded to the same technology that comes standard on the Hyundai Genesis sedan. We delved deeply into the internal hardware in 2015 Hyundai Genesis Sedan: Android, Atom, and More, but didn’t get to spend much time with the infotainment system until now.


As a refresher, it's powered by a custom-ordered Freescale i.MX53 SoC clocked at 1.1GHz. The i.MX53 is an evolution of the i.MX51 used by Ford SYNC and the older Kia UVO solution. The chip sports a single ARM Cortex-A9 core with Imageon Z460 graphics and an Android-based operating system that’s skinned to match Hyundai’s other infotainment systems.

Hyundai dubs the system in the Genesis sedan AVN 4.5, and AVN 4.0 on the new Sonata. The only difference between them is that the Genesis has more buttons for music sources, while the Sonata relies more on its touchscreen interface. As with the Genesis sedan, the 8-inch screen has a typical resolution of 800x480, which is sufficiently detailed from the driver’s seat.

This particular infotainment system features enhanced Blue Link capabilities that include destination search, POI Web search and download powered by Google. There’s even remote start through an iOS or Android smartphone application, automatic collision notification, enhanced roadside assistance and maintenance reminder services. Drivers who are concerned with their impact on fuel economy can access an information display that graphs detailed metrics for acceleration, deceleration, speed distribution and idle time.

Navigation is standard Hyundai fare, with flat maps that are adequate for daily driving, but not as detailed as the 3D maps available from competitors. Hyundai does add a split-screen view mode to put navigation and music functions side-by-side, which is a nice addition.

The infotainment system also supports Wi-Fi network connectivity for data-compatible applications. Unfortunately, there weren’t any Wi-Fi capable apps available for us to play with.

    Thanks for the informative review. My next mid-sized sedan will definitely be a Toyota Camry.

    Yuck, dont like the styling at all compared to the previous generation.
    To top it off the performance engine gets gimped.

    The Mazda 6 is still the best in my eyes, but the infotainment system they use is horrible. Toyota Entune is very dated as well.

    From what I've heard, the previous gen sold very well in the US but was a flop internationally, hence why they went back to more conventional styling. I don't expect them to sell many turbos this time around, or those that will don't care about raw output numbers.

    My next car will NOT be connected to the internet or any other cloud based technology. I can see it now - terrorists hack into multiple cars and initiate an acceleration virus....

    Or compromise Tesla's Autopilot system remotely...

    The new steering wheel controls look pretty similar to the '14 Kia Optimas, which I didn't really like.

    Not terribly impressed with the Apple solution if it requires USB. I probably won't like the Android solution either. but then I'm fairly happy with the various players being able to connect to a car stereo by BT. Smartphones change too much to buy a car based on what they are currently like.

    I wonder when the Sonata will be offered as a plugin hybrid not just hybrid and a lean burn engine not just Atkinson cycle

    UGLY! What the hell were the design engineers thinking? Far worse design versus ALL of the previous generation body styles. I don't give a crap about the interior design, if the outside of my car is going to look like that? Hyundai really needs to consider firing the moron senior engineer that allowed this ugliness to go into production. Damn.

    USB is a must IMO or you'll just have something very demanding draining your phone and pissed off customers wondering why their battery life sucks.

    Its rumored to come soon IIRC.

    Thanks for reminding some idiots out there to use their turn signals. I see at least 2 of 10 people not using turn signals all the time. This is in Portland, Oregon area.

    This looks like a desperate knock-off from a Ford Fusion. Watch Hyundai market the car with carefully-chosen slightly-better specs than other mid-size sedans. Thankfully I've had a chance to drive many sedans over the years, and I know that Hyundai is always the low end in every category.

    The 2015 Sonata also reminds me of Samsung's just-in-time attempts at copycat smartphones over the years. Can anyone in South Korea think original anymore?

    I despise driving in downtown Portland. I understand pedestrians have right of way and everything, but does nobody look both ways before diving into the street while texting on their phone?

    I don't think it looks like the Fusion at all. Hyundai has come a long way and the Sonata is competitive. It's more going after the Camry and Accord. I'd say the Fusion is more on the sporting side and not too big whereas the Camry and Accord have gone nearly full-size like the Sonata. Hell, the Sonata is almost as big as the Azera, which makes the higher end car only suitable for people that want V6 power. Now come to think of it, maybe they detuned the turbo to get more people in Azeras?

    In terms of reliability, quality, and resale value, you can't go wrong with a Toyota Camry.

    Hey I'm around Portland OR / Vancouver Wa too. Aggravating when someone comes in close in front of you without turn signals. A quick toot of my train horn releases my pressure

    A Toyota is always a safe bet if that's what you want. For me, the drive is too dull and boring to ever consider it.

    Which reminds me I need to find a set of Hella horns for the Project Mazda 5 and my wife's Leaf.

    Why would I buy a car from a Honda-rip-off company

    Hyundais don't even look anything like Hondas. All they are doing is competing, not ripping them off in any sense.

    Well, that raises another question--does the car's USB connection offer a 2.1 amp circuit?

    But in any case, for shorter trips I like the ability to just hop into the car and use a BT connection, not even touching my phone.

    I was once cut off by a no-signal lane changer. I caught up to him at a red light and called out the window "Your right turn signal is out." I meant it as sarcasm.

    He pulled over, checked his turn signal, and it was out. He thanked me. Glad I didn't curse him out for being to lazy to use it instead of my cool, understated sarcasm.

    Maybe May1 is just confused by the sound-alike name. ;)

    In any case, both companies make good cars, so that would be a reason to buy a Hyundai.

    Hornblasters sells the train horns, requires some space for the air system though. Someone managed to put the horns under the hood of a Smart car. I have the entire Shocker 240 system under the hood of my Civic.. Wanting to buy a used Volt, maybe put the horns and tank under the car just behind the battery and gas tank?
    Anyway it's quite an attention getter
